Books one, two and three in audio in Robert Muchamore's best-selling Cherub series.

The Recruit (Book 1):

A terrorist doesn't let strangers in her flat because they might be undercover police or intelligence agents, but her children bring their mates home, and they run all over the place. The terrorist doesn't know that one of these kids has bugged every room in her house, made copies of all her computer files and stolen her address book. The kid works for Cherub.

Cherub agents are aged between 10 and 17. They live in the real world, slipping under adult radar and getting information that sends criminals and terrorists to jail.

So when James Adams hits rock bottom, he's offered a new start at Cherub, and from there things start to look up.

Class A (Book 2):

When Cherub kids go undercover, no one suspects that they are trained professionals working to infiltrate criminal organisations that have eluded MI5 and the police for years.

James Adams is on his biggest mission yet, working to nail Europe's most powerful cocaine dealer. He'll need all his specialist training if he's going to bring down the man at the top.

Maximum Security (Book 3):

Over the years, Cherub has put plenty of criminals behind bars. Now, for the first time ever, they've got to break one out.

Under American law, kids convicted of serious crimes can be sentenced as adults. Two hundred and eighty of these child criminals live in the sunbaked desert prison of Arizona Max. In one of the most dangerous Cherub missions ever, James Adams has to go undercover inside Arizona Max, befriend an inmate and then bust him out.
